Module Description

This module was originally developed to enable registration between segmented MRI and transrectal ultrasound (TRUS) images of the prostate. The registration approach is based on hierarchical deformable registration of the smoothed distance maps of the segmentation masks (see details in the publication provided in the references section), and thus is not modality- or organ-specific, and can be applied in other applications.

Example visualization of MRI/TRUS registration result obtained using this module. Yellow outline is the contour of the manual segmentation of the prostate gland in TRUS, over the registered MRI image of the same prostate.

Use Cases

• MRI-ultrasound fusion biopsy of the prostate (primary)
• therapy planning
• treatment response assessment

Panels and their use

Fixed image (optional): image that should be used as reference in registration Segmentation of the fixed image Moving image (optional): image to be registered Segmentation of the moving image Registration affine transform: transform to store the result of affine registration Registration deformable transform: transform to store the result of deformable registration Visualization: initializes slice viewers to show overlay of the fixed and moving images (before or after registration), outline of the fixed image segmentation and the registration transform grid and visualization of the fixed and moving segmentation label surfaces in 3d view
